How to find Lenovo Battery Part Numbers?

Essential to the purchase of your new laptop battery is the part number. A part number is a unique identifier that is assigned to a part to simplify referencing and to unambiguously define a part within a single manufacturer. Knowing about part number of the battery will more accessible to buy a correct battery, and it is comparatively accurate to search a battery by its part number than the model name of laptop.

A laptop battery has at least one part number (that is, the battery model we often say), and many batteries even have multiple part numbers. When you find a battery with the same part number as your laptop battery, you can be sure that it is fully compatible with your laptop.

How do I remove the battery from my Lenovo laptop?

  • If your laptop is plugged in, either unplug it or disconnect the power cable.
  • Turn your laptop over so the bottom is facing up.
  • Locate the battery latch on the bottom of the laptop. The image above shows some of the more common battery latches found on laptops.
  • To remove the battery, slide the latch switch to the opposite side and hold it in that position until the battery is released.
  • On some laptops, the battery pops out on its own. On others, you'll need to pull it out gently with the tips of your fingers.

Lenovo often lists several part numbers, one is called "FRU p/n", on is called "ASM p/n", and occasionally the model number is just listed on the battery with no preface. Also on many Lenovo cartridges there is a red or orange circle with a number inside it (also may contain a + sign).
